RE: 10 degrees
Yes that was the winter of 95' at my house. That's looking out the kitchen window towards my shop and garage.
The deer here sometimes"yard up." Some of them have already started to gather. They gather in the deep woods in places that are somewhat protected by winds with lots of vegetation and brush. Then they stomp the yard flat and hard basically. Then theyhang together and browse on anything they can find. When we get bad winters the deer in the yards get in bad shape. It makes you almost sick when you find a deer yard that's browsed out... plus they eat snow and it dehydrates them and they often times just lay down. Even when you come in the yard since there is no where to run.
Also wolves will find the yards and they go in there and kill lots of the deer that are too weak to run off or escape. They can really leave a mess in there.
In fact in hard winters I will often go back in my woods and cut down four or five white or red cedar trees. They will eat the cedar buds and in the spring there is nothing left on them but large limbs.
When the snow is as deep as that one picture there, all you can do is snowshoe to get around. Unless you want to walk paths. And if you go into the woods, you better not fall over. Its hard to get up when you have to swim in that snow.
The following spring I had friends come and visit and they wondered what had girdled the popular trees five feet up the trunks. I told them it was rabbits that did that. And they looked at me like I was nuts. Then they asked how a rabbit could get that high up. So I showed them the pictures of the snow that year.
